to further answer your question, when you trade currency with Binary you aren't actually exchanging your currency for the currency being trades. For example, if you deposit in USD $100 your balance will be $100 USD and all trades will be made in USD, when you make a trade on the eur/usd your trade amount/wager will be in the currency of your deposit... so $10 usd on a call option for eur/usd, and your winnings will also be in USD. Your trading on the direction of the trade, not the actual exchange of currency. Make sense?
